26' is provided shaft 37, which projects through the housing, is provided with a square socket 38 into which the switch throwing lever 39 is secured. This switch throwing lever is preferably square and is provided at its outermost end with a weight 40.

The end of the arm 25, opposite the fork, is provided with a boss 41, this boss 41 being provided with a square hole 42 through which the target stand 48 projects. This target stand extends entirely through the boss 41, through a second boss 44 and into a lever 45. This lever is in turn secured to a rod or switch bar 46 which is connected with one of the switch points 47 and from this switch point 47, another bar 48 extends to the opposite switch point, thus causing both points to operatesimultaneously.

The housing 11 is further provided with a pair of projections 49 in which spring actuated lockin hooks 50 are located. Each of these spring actuated locking hooks is provided with an upwardly extending hook member 51 and a foot treadle 52. The pin 53 is secured to the upwardly extendmg locking member of the hook and operates simultaneously therewith. In other words, whenthe treadle 52 is depressed, the member 51 releases the switch throwing bar 39 and at the same time withdraws the pin 53. The pin 53 serves as an additional locking device, in that it secures the housing 21 from shifting, this being clearly shown in Fig. 1.

It is to be understood that my device may either be secured to two ties, as shown in the drawings, or the same may be placed sidewise and secured to only one tie and still be operative. Furthermore, I may extend the arm 45 on the opposite side of the laterally projecting housing and work a second switch simultaneously with the first switch without'departing from the spirit of my invention.

I may, if desired, provide the projections 49 with perforated ears 54, through which a locking device can be inserted and a switch stand securely locked, so that it cannot be tampered with, this being-expressly desirable when my stand is used for siding, or switches which are removed from railroad yards.

It will also be further observed that, when the switch operating lever 39 is locked as illustrated in Fig. 1, the pin 53 rests against one end of the movableor secondary housing '21 and the opposite end of said housing rests against the inside end of the housing 12, thus securely holding the inner housing 21, as it were, in locked position and when the switch operating lever 39 is reversed, the operation is repeated in so far as looking the secondary housing is concerned; it being noted, that the housing 21 is never locked unless the lever 89 is in locked position.

Having fully described my invention, what I claim is:

1. A. switch stand comprising a switch operating bar, an operating means resiliently connected to said switch operating bar, and a lever mechanism connected to said resilient means for placing the switch operating bar in operation.

2. A switch stand comprising a switch operating bar, an operating means resiliently connected to said switch operating bar, a lever mechanism connected to said resilient means for placing the switch operating bar in operation, and a means for locking the resilient means in position when the switch is thrown.

3. A switch stand comprising a housing, a lever mechanism located partially within said housing, a second lever mechanism located partially within said housing and resiliently connected to the first mentioned lever mechanism in combination with a pair of switch points to which said second men tioned lever mechanism is attached.

4. A switch stand comprising a housing, a second housing mounted within the first mentioned housing, said second mentioned housing being provided with a lateral slot, a rack carried by said second mentioned housing, a bifurcated lever pivotally mounted in the first mentioned housing and extending through the lateral slot formed in the second mentioned housing, a shock absorbing spring mounted on each side of the bifurcated lever and within the second mentioned housing, a bar for operating the points of a switch and a lever mechanism mounted in the first mentioned housing for shifting the second mentioned housing from side to side.

5. A switch stand comprising a housing, a second housing mounted within the first mentioned housing, said second mentioned housing being provided with a lateral slot, a rack carried by said second mentioned housing, a bifurcated lever pivotally mounted in the first mentioned housing and extending through the lateral slot formed in the second mentioned housing, a shock absorbing spring mounted on each side of the bifurcated le er and within the second mentioned housing, a bar for operating the points of a switch, a lever mechanism mounted in the first mentioned housing for shifting the second mentioned housing from side to side, and a means for preventing the second mentioned housing from shifting when the lever is thrown.

6. A switch stand comprising a switch point operating "bar, a switch throwing lever, a resilient lever connection between said switch bar and switch throwing lever, and means for simultaneously locking the switch throwing lever and the resilient lever connection,
